Ai Toon texturing, Mixing with Ai Standard

Hi,

I am quite new to the AiToon and I don't quite understand how to tackle my problem, considering I've already read the manual. I have a character with a base colour texture file that textures the entire character. I want to also use the AiToon to give it that 2D contour effect. Yes I already know about changing the render settings to contour. I don't want to over complicate the texturing process with ramps or have lots of textures for one model.

Do I need to add some kind of mixture node to allow the AiToon node to be linked to the AiStandard node? Or am I over complicating it. Please let me know what you all think and thank you very much.

Thanks for posting!

We suggest rendering the edge separately and compositing them together. This page could be helpful to you: https://docs.arnoldrenderer.com/pages/viewpage.action?pageId=71008401#AOVs%28Toon%29-RenderingEdgesSeparately

Using Toon means you need to use the Contour filter, so you'll be rendering a combination of the Standard Surface with the Contour filter and mixing them. Standard Surface returns a closure, not a color value, so you cannot plug Standard Surface into Toon.

In this example, we used a Passthrough node to force MtoA to convert the Mix shader to mix_shader instead of mix_rgba:

I hope that helps!
